That and religious ceremony are the only two common ones I'm aware of. Anything else and it can be used to throw the book at you in a lot of ways. I had a friend kicked out of our high school graduation because a teacher disliked him, convinced an officer to breathalyze him, and he blew a ~.02 if I'm remembering correctly. He'd had a beer with his parents at dinner before the ceremony, but by the time that was all sorted it was well after the ceremony had ended. Kid didn't walk the stage at his own graduation because of a power hungry teacher and a (legal) beer his parents gave him. In most states in the US having any alcohol at all in your system or being in possession of it is very much a crime and the burden of proof is on you that it was consumed legally.
